Add what you own. Log what you use.
Get advice that knows you. Earn points along the way.


Bring the context you choose from AI assistants, brand sites, social spaces and everyday apps into Hallie. Decide what connects, what it adds and when it stops.

Each one earns points. Each one makes the next recommendation sharper — here and everywhere else you shop.
Snap the bottle — Hallie reads the brand, name and size off the packaging. Or type it. Wishlist and Empties too.
Tick what you used, rate it, say how it went. Makeup gets two extras — how long it lasted, and how it looked by the end of the day.
She reads your profile, your quiz answers, your products and every log before she replies — so the answer is actually yours.
One per category — skin type, hair type, undertone, concerns, and your shade on the 10-tone Monk scale. This is the part that travels.
Add the products you actually own. Log what you use. Hallie learns your skin, your hair, your scent, your shades — then carries that with you, so the next brand you shop already knows what fits. And every bit of it earns you points you can cash out.
For consumers · Beauty first, the whole shelf next.
Build it once in Hallie. Every Halite partner brand you shop starts off already knowing your type, your tone, your concerns and what’s let you down before.
You decide when it travels — and you can switch it off, or take the whole thing with you, any time.
You’ve answered “what’s your skin type” a hundred times, for a hundred brands, and none of them remembered. Build it once in Hallie and it comes with you.
Every product, every log, every answer earns points. Payout availability and current terms are managed in the Hallie app.
You’re doing the work — you should be paid for it.
Anything you buy on repeat, use on a routine and form an opinion about is something Hallie can learn from.
Same shelf, same log, same quiz — a different set of questions per category. Every category we add is another one your profile can walk into pre-answered.
A streak, whatever the category. Any day you add, log or answer something counts — in your own timezone.
Beauty is where we started, because it’s where the questions are hardest — shade, texture, skin tone, sensitivity. But the mechanics don’t stop there, and neither do the brands on the other side of Halite.
Sharing with partner brands is a separate consent you grant yourself, and can withdraw the same day. Opt-in brand sharing is off until you turn it on. It only travels because you let it.
